THE WAY THE Vacuum Pump Works

1. What is the role of the vacuum pump? What kinds of vacuum pumps are generally found in refineries? The vacuum pump is made to create vacuum pressure in the equipment or container that works below ambient atmospheric pressure or high vacuum. Vacuum pumps commonly used in refineries include steam plane vacuum pumps, water ring vacuum pumps and reciprocating vacuum pumps.

2. What’s the working theory of the steam plane vacuum pump? It contains a nozzle, a mixing chamber, an growth chamber, and a pressure outlet. In operation, drinking water vapor is timing pulley certainly sprayed from the nozzle into the combining chamber at a higher speed (1200-1500 m/s). At this time, a specific negative pressure is produced at the nozzle, so that the pumped gas is definitely flushed into the blending chamber from the gas inlet and blended with drinking water vapor. And get some good energy from the water vapor. When the mixed gas stream enters the vacuum pump 2sk 6adiffuser chamber, the velocity gradually decreases along the axis, and the pressure steadily boosts along the axis stream until it really is discharged above the atmospheric pressure. Because of the continuous work, the gas in the equipment is continually extracted, thus causing a vacuum (negative pressure) state within the equipment.

3. What are the characteristics of the steam plane vacuum pump? The steam jet vacuum pump entrains the pumped gas at a higher speed of drinking water vapor, so it gets the characteristics of large pumping capacity, high vacuum, simple manufacture, convenient set up and maintenance, etc. Presently, the vacuum distillation device of the refinery Most of the vacuum pumps utilized are steam plane vacuum pumps.

4. What is the structure of the water band vacuum pump? What’s the working basic principle of the water ring vacuum pump? The water ring vacuum pump is composed of a pump casing, an impeller, a water band, a suction chamber, a discharge chamber, and a vent hole.
